Spring ’26 Platform Updates: Security, Automation, and What to Tackle First

To close out our Spring ’26 Salesforce Release Series, we are focusing on platform, automation, and security. If there is one area to prioritize after reviewing the rest of the release notes, this is the one to action sooner rather than later.

Why this Should Move to the Front of the Queue

This part of the release brings together required updates and meaningful operational improvements in a way that directly impacts how your platform runs day to day. Some changes directly impact access, email delivery, and integrations if left unaddressed, while others can reduce build time once the essentials are in place.

This becomes especially relevant as teams revisit platform priorities after Q1 and begin addressing questions around access, SSO, and overall security posture.

Three Breaking Changes Clients Cannot Ignore

Start with the mandatory updates. Salesforce now requires sending domains to be verified through DKIM or an authorized email domain. Without this step, Salesforce will not send emails from those domains, even if individual addresses are verified. For organizations relying on Salesforce for communications, notifications, or automated outreach, this is critical to maintain continuity.

Next is the shift away from legacy connected apps. New connected app creation is now disabled by default, and new integrations are expected to use the External Client App framework. Existing apps will require a migration plan, making this both a security and architectural consideration.

Finally, updates to host names and API routing mean temporary redirects for legacy Salesforce URLs are being retired. Any integrations or links still using older patterns should be updated to the organization’s My Domain login URL to avoid access or connectivity issues.

Automation is Getting More Practical

Alongside these required changes, Spring ’26 introduces more accessible ways to build and refine automation. Flow Builder now supports creating and iterating on record-triggered and schedule-triggered flows using natural language through Agentforce. MuleSoft for Flow extends similar capabilities to integrations with AI-generated templates.

These updates help teams move faster while maintaining control. Natural language assistance does not replace good design, but it can streamline the process of building and updating automation when requirements are already clear.

The Default Security Baseline is Rising

Salesforce is also strengthening its built-in security posture. New capabilities include native malware scanning for Salesforce Files and passkey-based passwordless login, both currently in beta.

Malware scanning helps prevent harmful files from entering or leaving the platform, while passkeys provide a more secure alternative to traditional passwords. Together, these changes reduce risk while improving the user experience.

A Practical 30-Day Response Plan

A focused response starts with visibility. Inventory integrations, SSO configurations, and any legacy connected apps. Confirm email domain verification and identify processes that depend on Salesforce-delivered email. Review host names, URLs, and hardcoded links for outdated patterns.

From there, identify a small number of automation opportunities where the new capabilities can accelerate delivery without adding risk.

Spring ’26 platform updates are not something to defer. They directly affect access, communication, integration stability, and how quickly teams can build going forward. Palladin helps organizations address immediate requirements while using this moment to modernize automation and strengthen security in a sustainable way.
